[HECnet] DECnet et al

No. By the endnode itself. It have no idea where to send it. For ethernet, DECnet supposedly already knows the MAC address where to send every packet. Where would it send a packet that isn't to the local ethernet segment? All the end node needs to know to send an Ethernet frame is a MAC for the destination, and if it knows the DECnet node number then it knows the MAC by definition. Anything beyond that is not its problem. That's what the bridge program does, right? Moves those DECnet Ethernet frames, via TCP/IP (or UDP - I forget which you used) over Internet to another LAN ? BTW, what do you mean by Ethernet "segment" in the context of the bridge program? Aren't bridged "segments" by definition the same segment (at least as far as DECnet messages go)? Or is the bridge itself doing something smart with DECnet traffic? Bob
